A Brief Introduction to Branched Oyster

Pleurotus cornucopiae

Also named Jigu, this specie belongs to Pleurotus, Pleurotaceae,Agaricales, Hymenomycetes,
Basidiomycetes. Branched oyster contains abundance nutrient composition, for
example protein, sugar, fat, vitamin, Fe and microelement. Amino acid content
is higher than that of vegetable, contains eight human necessary amino acids.
The context are thick, tender. It has favourable taste and healthful effects.
It is the most popular oyster.

Its cultivation technique is introducing below:

Cultivation technique:

1. Strain choice:

There are lots of strains in production at present,
and the Japanese strain, which cultivated in our province, now is more
ideal strain.

3.Cultivation season:

The fruit body fruiting phase is short in every
flash. The nutrient composition expenditure is low, and the flush is short,
too. So the whole cultivation stage pulls long very much, and it is 6
months at least. At area which air temperature is low it may be last 10
months. In order to sufficient using the nutrient of the mediums the temperature
of spawn running phase don't exceed 25°C. The scheme are arranged base
on the adopted strain, air temperature and production condition.

4. Cultivation place:

Adopting indoor bed cultivation or outdoors shed
cultivation. Indoors bed cultivation refers to the stacking method in
Negraudia reymaudiana cultivation. Outdoor shed cultivation adopts ridge
cultivation or stacking cultivation. The cultivation place is on high
site, faced the south and using water and draining easily. Keeping off
pollution resource. Creating an ecosystem benefit to hypha growing and
disbenefit to germ growing.

5.Cultivation method:

Adopting the processed substance bag cultivation.
It can short the flush. The structure of cellulose and lignin is changed
after high temperature sterilization. It is benefit to mycelium decomposing,
absorbing, utilizing.

6. Filling and sterilization:

According to the formula weighing the substance.
Moisture content is about 65%. The bag is 17×33 cm polypropylene
bag. Filling 300-400 gm dry substance in the bag, sterilizing by high temperature
steam. It is best to do that filling and sterilizing intraday. The temperature
rises 100°C, keeping stability and maintaining 14-16 hours. After sterilizing,
cooling. When the temperature is under 28°C, inoculating according to
inoculation operation demands in time. Spawn running in running room at
25°C after inoculating, keeping away from the ray.

7. Fruiting management:

After impregnation in the running room the suitable
temperature, humidity, ray, aeration induces, the hypha come into physiology
maturation. It takes about 7 days. Put the bags into mushroom house, stacking
on bed like the wall. It is five bags high. It is difficult that the button
form when the temperature is lower than 15°C in the house. When the temperature
is higher than 30°C, taking aeration to cooling down. It is effective to
taking aspersion and atomization, too. Don't atomizing into the bag otherwise
the button yellow and die. At the same time, it is taking aeration to
refresh the air.

7.1 The phase of primordial differentiation:

On stage of the hypha coming
into physiology maturation and recreation, enlarging temperature difference.
And cooling the temperature of environment to 5-10°C. Giving definite scatter
ray to let the hypha of the mediums surface down so that adequately induce
to primordial.

7.2 The phase of button forming:

Making every effort to decrease temperature
difference and humidity difference. Keeping the temperature on 18-24?
and humidity on 85-90%. Spraying three times every day. When the water
accumulating on the surface of the medium, dry or pour out in time.

7.3 The phrase of fruit body growth:

When the button grows like a peanut,
the humidity can undulate 75%-95%. In this range, the temperature and
humidity are higher in this range the fruit body grow thicker. Ridge cultivating,
the ventilating windows open 5 cm high in day and open 10-15cm high at
night. Indoors cultivating the ventilating windows open full, at night
and open half in day. So that the temperature and humidity of cultivation
environment are higher in day and those are lower at night.

8. The diseases and insect pest's prevention and cure:

8.1 The phase of spawn running in bag:

The familiar competitors contain
Trichoderma, Penicillium, Mucor, Streptomyces and Neurospora sitophila
etc. Discovers can using 0.5-0.7 cm wood rod or iron rod, in the contaminative
bags on all sides and firm 5-7 deep bore of cm, then press the bags originally
the form line up to rise, when the outsider environment term is in keeping
with, through educating of 3-5 days assesses, normal mycelium just start
running the compost , again over the hair of 10-15 days assesses, bags
full become pure.

8.2 The phase of fruit body fruiting:

The familiar competitor is Myxomycete.
The polluted cultivation bag is disposed when discovering Myxomycete.
At the same time strengthening aeration. The familiar pests contain slug,
snail, Drosophilidae and Phorids. Using the 25 ppm Turbair permethrin solution
to prevent. Atomizing before fruiting or after harvesting. Don't atomizing
the fruit body.

8.3 Harvesting and process:

The product is primarily exported. Its quality
is demanded highly. In general, pileus diameter is under 2 cm. It is the
most suitable time to harvest, when fruit body only forms and before the
fruit body elongate fully. At the same time batch collecting in time to
improve the fine product yield. After one flush cleaning the medium surface
for the next flash. It is six flashes in a cultivation period. The general
biological efficiencies can achieve above 100%.
